WINDOW-VENTI LAT@ R.

SPECIFICATION forming part of Letters Patent No. 597,145, dated January 11, 1898.

Application tiled October 26, 1896. Serial No. 610,045. (No model.)

To @ZZ whom it may concern:

Be it known that I, Montare H. HARTZELL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention has reference to a novel construction in aventilator adapted for use in connection with sliding windows; and it consists in the features of construction hereinafter described and claimed;`

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of a ventilator constructed in accordance with this invention. Fig. 2 is a vertical transverse section, and Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 2.

This device is intended to be placed at the upper or lower end of a window-frame and between the upper or lower end of the sash and the adjacent end of the Window-frame.

The deviceis made adjustable longitudinally, so that it ts windows varying in width and serves to ventilato, while at the same time it will exclude iiies and insects.

Referring 'now to said drawings, said ven tilator consists ot' two frames 1, adapted to slide upon each other. These frames are counterparts of each other and are provided with overhanging anges 2, that engage the top edge of the other member, and with 'end' `lian ges 3 to engage the end of the other member. In this way the members are iitted together so that they can slide. The said frames are provided at their upper and lower ends with longitudinal grooves et, that receive pins or projections 5 upon the other member to hold these parts rmly together that they may move longitudinally with relation to each other. To hold the frames in their adjusted positions, they are provided with longitudinal slots 6, through which pass pins 7, fastened to the other member and provided with the thumb-screws 8, that serve to clamp the members together. The frames are covered with a Wire-netting 9 to exclude iies and insects, and the said frames are also provided with overhan ging hoods 10, fastened along the upper edge of the frames,.as shown in Figs. 1 and 2. These hoods extend downwardly and outwardly to a point near the bottom of the frame and are held at their ends by braces 1l, secured thereto and to the end of the pieces of the (frame. These hoods are adapted to slide with relation to each other, being carried by the sliding frames, and at the top of the frames one of said hoods is provided with an overlapping tongue l2,between which and the top rail of the frame the tongue 13 of the other hood is situated. The ends of the frames'are provided at the lower end portions with recesses 1e, in which the wiudow-cords are situated when the ventilator is placed in the upper end of the frame. On the outside thereof are two deiiecting-plates consisting of two sections 15 and 16, that are attached to the frames 1. These plate-sections 15 and 16 extend from the lower end of the ventilator to about one-half of the way between the top and lower edges of the screen 9. The section 16 is provided with key-slots 17 to receive the headed pins 1S upon the outer frame l, while the end of this section 16 is provided with the iiange 19, situated within the guide 20, carried by the end plates 21 of the hood. The plate-section 15 is attached at its outer end to the other end of the hood in a similar manner and is provided at its upper edge with a ange 22, that rests upon the upper edge of the plate-section 16. It will be seen, therefore, that this plate-se@ tion 16, being held' by means of the headed pins 18, will support the other plate-section in an obvious manner.

It will be seen from the foregoing description that a Ventilating device of this kind in the first place is adjustable to windows of different size, and, furthermore, that it can be readily placed in position at the upper or lower end of the window-frame and between said frame and the end of the Window-sash and will allow sufficient ventilation, while at the same time it excludes iiies and insects from the room. The frames of the ventilating device iit nicely and slide readily, while the dedecting-plate can be removed when not needed-for instance, when the device is placed at the upper end of the window-frame.

IOO

lWhen the device is placed at the bottom of the Window, this deecting device is useful, since it prevents the rain from splashing into the room after striking the sill, so that in connection with the overhanging hood the rain is effectually excluded.

The device is simple and inexpensive and can be made in a durable manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A ventilator consisting of two relativelysliding frames, said frames being provided with overh angin g hoods that overlap and slide with relation to each other, and screens carried by said frames.

2. A ventilator consistin g of two relativelysliding frames provided with screens, and recesses in the lower end portions of said frames to receive Window-cords.

3. A ventilator consisting of two relativelysliding frames provided with screens and with overlapping and overhanging hoods, and uprising and overlapping deiiecting-plates secured to said frames opposite the lower end portion of said screens.

4. A ventilator eonsistin g of two relativelysliding frames provided with overhanging hoods, and uprising and overlapping deflectin g-plates removably secured to the lower end portions of said frames.

5. The combination with the relatively-sliding frames of a ventilator, of a deflecting platesection secured to the =lower end portion of one of said frames, and a deiiecting plate-section secured to the end of said other frame and provided with a flange resting upon the upper edge of the irst-inentioned deilecting plate-section.

6. The combination with therelatively-sliding frames of a ventilator, of headed pins and an upright guide upon one of said frames, a deiecting plate-section provided with keyslots and an end flange, the other of said frames being provided with an upright guide, and a deflecting plate-section having an end iiange situated within lsaid last-mentioned guide and having an upper flange resting upon the upper edge of said first-mentioned deiiecting plate-section.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
